Hello everybody,

Quick question. I plan on a new 7.5g. At places the substrate may reach 6 inches . I plan on putting some powersand on the bottom and then topping off with Amazonia Powder. I want the powder variety as the smaller grains make a small tank look bigger. But am worried that small grains+ deep substrate will create problems in the long run ? (Maybe even some nice anaerobic farm in my own tank.)

Any experience or opinions welcomed.
